Match the oxy-acids of phosphorus listed in column I with type of bond(s) listed in column II

Column I (Oxy acids of phosphoros)	Column II (Characteristic bonds)
\[{{H}_{4}}{{P}_{2}}{{O}_{7}}\]	(p) P - P bond(s)
\[{{H}_{4}}{{P}_{2}}{{O}_{5}}\]	(q) P - 0 - P bond (s)
\[{{H}_{4}}{{P}_{2}}{{O}_{6}}\]	(r) P - H bond(s)
\[{{(HP{{O}_{3}})}_{n}}\] (cyclic)	(s) Three or four P - OH bonds

A) \[A\to q,r;B\to q,r,s;C\to p,s;D\to q,s\]

B) \[A\to q,s;B\to q,r;C\to p,s;D\to q,s\]

C) \[A\to q,s;B\to q,r,s;C\to p,q;D\to r,s\]

D) \[A\to q,r;B\to q,s;C\to r,s;D\to p,q\]

Correct Answer: B

Solution :

[a]\[{{H}_{4}}{{P}_{2}}{{O}_{7}}\] [b]\[{{H}_{4}}{{P}_{2}}{{O}_{5}}\] [c]\[{{H}_{4}}{{P}_{2}}{{O}_{3}}\] [d]\[{{(HP{{O}_{3}})}_{3}}(Cyclic)\]
